I had the same issue twice with a TH 42PWD5. turns out it was my UPS that was killing the switching power supply. Warranty covered it but when I removed the UPS not a single issue in 3 years.

Bad capacitors...! Remove rear panel cover from tv. Most require a star screwdriver. Look for bulging caps in power supply board. (3300uf 10v ) caps need to be replaced with 3300uf 16v. Identify the bad caps.... Caps are bad when they are bulged/bulged and raised. A good Cap is flat X top not raised or buldged. I have pics of what bad caps look like on these boards. Email me if you would like to to see them. Caps cost abywhere from 1-2 dollars or you can buy them in lots of 10 or 12 on ebay for around 8 bucks. Caps need to be soldered on. Do it yourself (if confortable) or take it to a tech/pc repair shop in your local area. Do do that unplug all the wire harness from the board and unscrew the boarda nd take to your teck to solder on the new caps.
You can fix this for about 20 bucks if you have someone else solder or 40 cents if you buy the caps on ebay and replace the 2 bad ones yourself. If one is bad and the other is not replace them both.
The caps go bad because they need to be a higher voltage. 10 insn't enough..... 16 is plenty and don't go any higher than that.

are you using a PC to feed a signal or maybe a cable with an adapter?
I had the same issue when I used one of the rear HDMI ports to show a PC display. Apparently there is a software difference between the rear and side/front ports. Inputting the PC through the side HDMI port has solved the problem for me (so far!)

I had this problem in 2007 / 2008 here is what happened to me.
Jan 09, 2008 - I also have brought the unit to the authorized Panasonic repair facility and the problem is a failure in the P-board which is the power supply board. The P-board needs to be replaced. The repair will cost $475 plus tax. $250 is for labor. The unit was nop more than two months out of warranty. This does not speak well for Panasonic. I have been researching the problem and it looks like this has happened to many of the Panasonic plasma TVs.
Jun 14, 2008 - As an update to my problem with the failed P board. Contacted Panasonic Service and talked to a customer service representative. I told them how I have purchased many Panasonic products and how unhappy I was with the failure of the product. They proposed paying the labor cost of $250 and I would pay for the part. I just hope it does not happen again.
